What two special image are formed by concave mirror? Concave mirrors can produce both real and virtual images; they can be upright (if virtual) or inverted (if real); they can be behind the mirror (if virtual) or in front of the mirror (if real); they can also be enlarged, reduced, or the same size as […]
Why do we need SI unit?
Why do we need SI unit? SI unit is an international system of measurements that are used universally in technical and scientific research to avoid the confusion with the units. Having a standard unit system is important because it helps the entire world to understand the measurements in one set of unit system. What is […]
How does cyber security affect us?
How does cyber security affect us? Cyber threats are a big deal. Cyber attacks can cause electrical blackouts, failure of military equipment and breaches of national security secrets. They can result in the theft of valuable, sensitive data like medical records. They can disrupt phone and computer networks or paralyze systems, making data unavailable. Is […]

Does tin foil block 5G?
Does tin foil block 5G? Tinfoil can block the transmission and receipt of electromagnetic field (EMF) radiation and radio frequency (RF). 5G enables connectivity by transmitting and receiving radio waves or radiofrequency electromagnetic fields with base stations. By blocking these emissions, it will block 5G. Are Faraday cages legal? The effect was discovered in 1836 […]
What is Isrelaxation time?
What is Isrelaxation time? Relaxation time is the time gap between two successive electron collisions in a conductor. The relationship between the relaxation time (T) and drift velocity (Vd) is given below. What is the symbol of relaxation time? (i) Relaxation time (τ): In the absence of an external electric field, the free electrons in […]
What is a healthy breathing rate?
What is a healthy breathing rate? Normal respiration rates for an adult person at rest range from 12 to 16 breaths per minute. Does your oxygen level drop when exercising? The oxygen level in your blood decreases slightly while exercising because physical activities lower the amount of oxygen that binds to hemoglobin. When you’re working […]
What 3 parts are in a nucleotide?
What 3 parts are in a nucleotide? Nucleotides are composed of three subunit molecules: a nucleobase, a five-carbon sugar (ribose or deoxyribose), and a phosphate group consisting of one to three phosphates. The four nucleobases in DNA are guanine, adenine, cytosine and thymine; in RNA, uracil is used in place of thymine. Which of the […]

Where is the magnetic field in a coiled current carrying wire the strongest?
Where is the magnetic field in a coiled current carrying wire the strongest? The magnetic field is strongest inside the coil. This is because the effects of both sides of the vertical part of the wires add up at the centre. What are the advantages of electromagnet over permanent magnet? The main advantage of an […]
